Eugène Freyssinet is widely known as an important figure in the development of prestressed concrete. However, his contribution to engineering is immensely larger than the development of a specific technique. This review of his work shows that the development was part of his lifelong quest to use materials to their utmost capacity. As evidence, the author discusses Freyssinetâ€™s experiences with arch bridges and how they contributed to his understanding of creep, eventually leading to his insight that high-strength steel is needed for permanent prestressing. Freyssinetâ€™s prestressed concrete products, projects, and technologies are also discussed.
